I have a set of Nexgens just like this...
Link that I purchased from Mr.PokerChips. We used them for well over a year at my home game and they still look like new today. I've since upgraded to a set of Desert Sands, but the Nexgens are still really nice chips for the price. They feel good and do not have that metallic "clink" that most of the dice chips do. You can check out a couple websites such as
http://21ace.com/ and
http://www.chiptalk.net/ and you'll find reviews for the Nexgens and you'll see they are highly rated. They are also very popular because they are the easiest/best chips to have custom labels printed for.
I really don't think you'll go wrong with a set of these chips. They guys at my game loved them and were sort of sad to see them go. I just got an insane deal on the Desert Sands that I couldn't pass up. Now I've got a buddy asking me to sell him my Nexgens.
Good luck
